SPECIFICATION forming part of Letters Patent N 0. 597,664., datedJanuary 18, 1898. Application filed November 2, 189 6. herial No.610,889. (No model.)

To all whom, it may concern:

Be it known that we, FREDERICK F. AN DERsON, of Kansas City, Jacksoncounty, Missouri, and THEODORE KRAUSS, of Argentineflvyandotte county,Kansas, have invented certain new and useful Improvements inType-lvriting Machines, of which the follow: ing is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part thereof.

Our invention relates to type-writing machines; and our object is toproducers machine of this character by which a greater amount of workcan be done than with the type-writing machines in general use in thesame length of time and which is positive and reliable in operation.

A further object of the invention is to produce a typewriting machinewhich is simple, durable, and can be manufactured and sold for much lessthan any other standard machine on the market. i

To these ends the invention consists in certain novel and peculiarfeatures of construction and combinations of parts, as will behereinafter described and claimed.

In order that the invention may be fully understood, we will proceed todescribe it with reference to the said accompanying drawings, in whichFigure 1 represents a plan view of a typewriting machine embodying ourinvention. Fig. 2 represents a vertical section of the same, taken onthe line 11 II of Fig. 1 and partly broken away. Fig. 3 represents avertical cross-section taken centrally of the machine. Fig. t representsa horizontal section taken just below the top plate of the machine. Fig.5 represents a vertical section taken through the cable-wheel and alsoshows the carriage thrown back to the position it occupies when exposingthe printed characters. Fig. 6 represents in detail a View of one of thetype-levers and its operative connections and support. Fig. 7 is aperspective View of one of the shafts provided with one of our improvedkey-levers. Fig. 8 is a detail perspective view enlarged'to show moreclearly the construction and relation between said key-levers and shaft.Fig. 9 is a cross-section of the same, taken on the line IX IX of Fig.8. Fig. 10 is a detail view of the ballbearing support for the frontside of the carriage. Figs. 11, 12, 13, 14., and 15 are detail views.Fig. 16 is a detail sectional view to illustrate clearly the spring forreturning the carriage back to its starting-point at the proper time.Fig. 17 is a detail perspective of the carriage-frame. 7

Like numerals designate corresponding parts in all of the figures.

1 designates the bed or bottom, 2 the back, and 3 the top plate of atype-writin g machine.

4: designates a forwardly-projectiug horizonial shaft, which is securedin any suitable manner centrally to the back plate, and

mounted rot-atably thereon is a belt or cable wheel 5, preferably onrved, as shown, and proslot 6 in the top plate. Said Wheel is providedor formed integrally with a ratchet-wheel member 7. Mounted pivotallyupon saidshaft at the front side of the said wheel is a walkin gbeam 8and it is held reliablyin place by means of a retaining-nut 9. Saidwalking-beam at one end is provided with a pin 10, on which is pivotallymounted a gravity-pawl 11, engaging the ratchet member of said wheel.The opposite end of said walking-beam is pivot ally connected by apull-rod 12 to the front end of the arm 13 of a shaft 14. Said shaft isjournaled in the upper end of a U -shaped bearing-bracket 15, secured tothe bed-plate of the framework. A swinging frame 16 is mounted pivotallyupon said shaft and is connected by means of a comparatively stiffspring 17 at its lower end with the free end of the arm 13. By thismeans it is obvious that by moving forward the lower end of the pendentframe 16 the shaft 1a is rotated and the arm 13 moved downwardly untilit comes in contact with the stop-pin 18. Further movement of said shaftand arm is thereby arrested; but the pendent frame continues to moveforwardly until the type-lever has come in contact with and made therequired impression upon the paper. The object of the arrangement of themechanism j ust described will be explained hereinafter and also themeans for causing such movement of the swinging frame.

The carriagesupport and transverse adj uster are constructed asfollows-that is to say, 19 designates a bar which is normally held bymeans of the springs 20 against the rear side of the back plate of themachine, said springs, as illustrated clearly in Figs. 2 and 4, beingattached at their front ends to pins 21, depending from the top plate,and at their rear ends to eyebolts 22, projecting through the back wallof the frame and se cured by retaining-nuts 23 to said bar 19. At itsopposite ends said bar is provided with the arms 25, which projectforwardly through openings 26 in the back wall and extend throughguide-clips 27, secured to the under side of the top plate, as shownmost clearly in Fig. 2. arm the bar 19 is provided with an upwardT-shaped extension 28, which extends transversely of and overlaps thetop plate at one end,preferably,and j ournaled vertically upon saidT-shaped extensions or arms are flanged guide-rollers 2S). 30 designatesa bar which extends longitudinally of the machine and is supported byand between said guide-rollers, and is provided at its opposite endswith the forwardly-projecting and depending arms 31, to which areattached the opposite ends of the belt or cable 32, extending around thebelt or cable wheel 5 and preferably secured rigidly at a suitablepoint, as shown at 33, to prevent any slipping movement that mightotherwise take place.

The carriage-frame comprises the longitudinal bar 34, arranged justabove the top plate and a suitable distance in advance of and parallelwith the bar 30, the upwardlyprojecting arms at its opposite ends andthe rearwardly-proj ectin g inverted- L-shaped arms 36, which arehinged, as shown at 37,,to the arms 38, projecting rigidly upward fromthe bar 30. A shaft 39 is journaled in said transverse arms 36 of theframe, and mounted rigidly thereon is the paper cylinder 40. Mountedrigidly also on said shaft at the end of the cylinder toward which thecarriage travels in printing operation is a spirallytoothed cam-wheel41, and said wheel is preferably incased in a frame 42, carried by thecarriage-frame. The corresponding end of the shaft is also provided,preferably, with a head in the form of a milled disk or wheel 43,whereby the paper may be adjusted, if desired.

The carriage-frame is provided with a ballbearing at its front side inorder that it may freely move back and forth or longitudinally. Thisball-bearing comprises the hemispherical cap 44, provided with ananglearm 45, the ball 46, which fits into said hemispherical cap orsocket and upon the top plate of the framework, and the annular band 47,provided with a horizontal arm 48, said band encircling said ball snuglybelow its center and having its arm 48 fitting against the horizontalarm of the angle-arm and secured permanently thereto and to the middleof the bar 34 of the carriage by rivets (not shown) A short distanceinward from each or in any other suitable manner. By this arrangement itis obvious that when the carriage is elevated in order to expose thework or for any other reason the ball-bearing is elevated from the topplate of the machine without danger of the ball dropping out ofposition.

In order to maintain the paper in the proper position with relation tothe cylinder or feedroller 40, the roller 49 is arranged at the rear andupper side of said cylinder and is journaled at its opposite ends inbearings formed at the rear ends of the plates 50, resting upon the arms36 of the carriage-frame, said plates being provided with slots 51,which engage guide screws or pins 52, projecting upwardly from saidarms. In order to hold said roller toward the cylinder with a yieldingpressure, a pair ofretractile springs 53 are employed, said springsbeing attached at their front ends to the foremost bolts or guide-pins52 and at rear ends to lugs projecting from the bearings of saidrollers, as shown clearly in Fig. 1. At the front side of the cylinderand below its center is arranged a second guide.

roller 54, said guide-roller being journaled in a bracket 55, secured tothe bar 34 of the carriage.

Arranged longitudinally and below the center of the cylinder is asegmental platen or plate 56, and said platen is held rigidly in suchposition by means of the arms 57 57, which connect its opposite endswith the arms 36 of the carriage, as shown most clearly in Figs. 3 and5. Said platen may be of any suitable material which provides therequisite stiffness, and preferably at its center is provided with alongitudinal rib 58, which forms the platen or printing-surface proper.This rib will preferably be of rubber and of width only to cover asingle type at a time, so that it will be impossible for two impressionsto be'made upon the paper at one key depression. WVhen the carriage isin its normal positionthat is, in the position it occupies when thesmall letters are being printed the platen is over the front end of thetransverse slot or elongated opening 59 in the top plate, as shownclearly in Fig. 3. Vhen capital letters are to be impressed upon thepaper, the carriage is moved, in the manner and by the mechanismhereinafter described, rearward until said platen is vertically over themiddle of the slot, and when figures and punctuation-marks are to beprinted the carriage is moved rearwardly until said platen is over therear end of said slot, as will be hereinafter more fully explained.

Referring now to the ribbon-feeding mechanism, 60 designates a pair ofbrackets which are secured to the bed-plate of the machine in advance ofthe belt or cable wheel, and 61 a shaft journaled therein and carrying areel 62 and ratchet-wheel 63, which ratchet-wheel is engaged by agravity-pawl 64, pivotally mounted on an arm 65, projecting rigidly fromthe extension of the shaft 14, hereinbefore described, as shown clearlyin Figs. 2 and 4. A pair of brackets 66 are secured upon the top plate2, and journaled upon a shaft therein is a reel 67. The opposite ends ofthe ribbon 68 are attached to said reels, said ribbon extending from thetop reel through an opening 69 in said top plate and rearwardly beneaththe same to a point just in advance of the slot 59. At such point itextends upwardly through an opening 70 in the top plate, thencerearwardly through the opening 59, and down again through an opening 71in the top plate to the reel 62, as shown clearly in Fig. 3. By thisarrangement it is obvious that each forward movement of the frame 16,and consequent oscillation of the shaft 14, causes, through the mediumof the pawl 64 and the ratchet-wheel 63, a rotatable movement of thereel 62 and a longitudinal movement of the ribbon.

It is obvious from the peculiar arrangement of the ribbon-that is, fromits frictional contact in several places with the framethat it will beunnecessary to provide a brake to check the movement of the reel 67, assaid reel never acquires sufficient momentum to loosen the ribbonthereon.

72 designates ashaft which extends transversely of and a slight distanceabove the bed-plate and is journaled at its opposite ends inbearing-plates 74 or their equivalents. Mounted pivotally upon saidshaft are the arms 75, and said arms are pivotally connected by means ofthe links 76 with the depending arms 7'? of the shaft 78, said link 76being provided with longitudinalslots 76, which fit loosely upon pins '76 of said depending arms. The shaft 7 8 is journaled in bearing bracketsor sleeves 79, secured to and projecting forwardly from the back wall 2of the frame, and said shaft is also provided with theupwardly-projecting arms 80, having longitudinal slots 81 in their upperends,

'which pivotally engage pins 82, projecting laterally from theforwardly-projecting arms 25 of the bar 19. Projecting forwardly fromsaid arm are levers S3 and 84:, and carried thereby at their outer endsare the keys 85 and 86, respectively. By depressing the key 85 thecorresponding arm 75 is pivotally operated and through the medium of itsc011- necting-link 76 rotates the shaft 78 and, overcoming theresistance of the springs 20, moves the bar 19, and consequently thecarriage, rearwardly until the platen 5S occupies aposition over therear end of the slot 5.). When in this position, which is maintained aslong as said key is depressed, figures, punctuationmarks, and othersymbols may be printed upon the paper, which extends between thecylinder and the rollers 4.9 and 54 and against the face of said platen,as shown clearly in Fig. When said key is released, the springs 20return the carriage, said key, and the connected parts to their originalpositions. It will be observed in this connection that, owing to thefact that the links 76 are provided with the slots 7 6, the operation ofthe key 85, and consequently the depending arms of said rock-shaft, doesnot affect the position of the key 86, as the pin of the arm engagingthe same slides inoperatively in its slot. The same is true of the key85 when the key 86 is depressed. The only difierence in operationbetween the said keys is a difference of degreethat is to say, thedepression of the key 85 throws the carriage back twice as far as thedepression of the key 86. The depression of the latter key throws theplaten over the center of said slot 59, in order to receive impressionsof capital letters,as will be readily understood.

Arranged rearwardly, preferably, of the shaft 72 andjournaled,preferably,in the same bearing-plate are shafts 87, and eachis provided for its full length with a longitudinal slot 88 and with anupwardly-projecting arm 89, and said arms are connected, through themedium of the adjustable clips 90 and the rods 91 with the swingingframe 16, hereinbefore referred to. Said rods extend through aperturesin said frame and are provided with heads or enlargements at their rearends, as shown at 92. Mounted upon. said shafts are the requisite numberof forwardly-project ing key-levers 93. Said key-levers loosely encirclesaid shafts and are each provided with a tooth or lug 94, which projectsinto the slot 88 of its corresponding shaft, said teeth or lugs beingnarrower than said slots and normally resting upon or against theshoulder at the lower side of the slot in order that when one key isdepressed the shaft may be operated the requisite distance to cause itscorresponding arm 89 to operate the swinging frame 16 without affectingthe position of any of the other key-levers upon said shaft. In otherwords, the depression of one of said keys causes the shaft to rotateuntil the shoulder at the upper side of the slot reaches the tooth ofthe remaining levers, which consequently are not moved, and as the keyis released said swinging frame rotates the shaft back to its originalposition and consequently relevates the key. The operative relationbetween said shafts and keys will bemore readily understood by referenceto Fig. 9. In perspective view it will be noticed that the keys occupytheir normal positions relative to the shaftthat is, the keys rest uponthe shoulder at the lower side of the slot. In sectional view it willbenoticed that one key is depressed and the shaft rotated until the uppershoulder of said slot comes against the tooth of the other key, whichhas not been moved. Immediately the depressed key is released the shaftmoves back to the positions shown-in dotted lines and its lower shoulderor wall comes against the under side of said tooth, the depressed key,of course, being reelevated. The relative distance between said keys ismaintained continuously by the spacing sleeves or cylinders 95, whichencircle the shafts, as shown clearly.

The key-levers carry at their outer ends vertical rods provided withkeys 96 at their upper ends. Said keys, like the keys 85 and 86, alreadyreferred to, are of elongated form from front to rear in order that eachkey may have inscribed thereon three characters or symbols-viz., a smallletter, a capital letter, and a figure or punctuation-mark and that morespace may be left between said keys than is provided when circular keysare used, and consequently there is less opportunity for an operator inrapidly operating a machine to strike two keys simultaneously. Byelongating said keys their width obviously may be lessened, and in orderto provide a more natural bearing for ones fingers said keys arepreferably concaved slightly, as shown. The key-levers are guided in thevertically slotted guide bar 97, extending transversely of thebed-plate, and are each connected by a rod 98 to a U-shaped clip 99,preferably of spring metal. Said clip embraces and is pivotallyconnected to the heels of the type levers 100, which levers are providedeach with three type 101, 102, and 103, respectively, for printing smallletters, capitals, and figures or punctuation-marks. Said type-levers100 are embraced at their opposite sides by spring-clips 104 and arepivot ally mounted on pins 105, carried by said clips. The clips arefitted up against the bottom of the top plate and are so secured bymeans of screw-bolts 106 and clamping-nuts 107, said clips beingarranged in a curved line, as shown.

In order to insure that the type will strike the ribbon at the properpoint, a pair of guiderollers 108 are arranged below and at oppositesides of the slot 59 in the top plate,-as shown clearly in Figs. 2 and3. By this arrangement it is obvious that the letters imprinted upon thepaper will all be in perfect alinement, as the type will be guidedaccurately to its proper point by means of said rollers. The type-leversare limited as to downward movement by the usual stop-bar 109, which issecured at its opposite ends in any suitable manner in the verticalstandards 110, forming part of the framework.

' In order to return the carriage back to its proper position for thebeginning of a new line, we preferablyarrange around the shaft or axle 4and around the hub 111 of the wheel 5, as shown in Fig. 16, a stiffspiral spring 112 and secure its opposite ends to pins 113 and 114,secured, respectively, to said wheel and to the back wall of theframework. As the carriage is moved forward with each depression of akey or of a spacing-bar 115, provided with levers 116, secured rigidlyto the shaft 72, the rotation of the wheel 5 winds up said spring, butowing to the fact that it is of greater diameter than the hub which itencircles it is obvious that there is no frictional contact between itand said hub, and consequently the keys may be depressed more easily andrapidly than in any machine which employs an ordinary barrel or clockspring for this purpose, though it is understood, of course, that we mayemploy an ordinary clock-spring in lieu of the spring 112, if desired.Such a spring we have illustrated in Figs. 3 and 4 and numbered it 117.Said spring is secured at one end, preferably, to the stationary shaft 4(the hub of the wheel 5 being dispensed with) and at its opposite end tosaid wheel 5.

To return the carriage to its original position at any time, we haveprovided a special key 118, mounted at the free end of a lever 119,which lever is pivotally connected to an arm 120, projecting rigidlyfrom one of the shafts 87, as shown clearly in Fig. 4. Said arm is alsopivotally connected bya link 121 to the depending arm 122 of the shaft123, said shaft being mounted in a bearing-bracket 124, secured to thebed-plate, and having a horizontal rearwardly projecting arm 125,connected by a rod 126 to the arm 127 of a pawl or dog 128. Said dog ispivotally mounted, as at 129, upon a bracket 130, secured to the backwall of the casing, and engages the ratchet-section 7 of the wheel 5just below and in the vertical plane of the pawl 11, so that by theoperation of said return-key 118 the 'dog 128 trips the pawl 111 andpermits the spring 112 or 117, as the case may be, to rotate the wheelbackward, and consequently return the carriage to its original position,the carriage being arrested at the proper point by means of the stop-pin131.

In order to automatically rotate the cylinder and consequently space foreach newline, a sliding bar 132 extends through the frame 42 and inlongitudinal :alinement with a bracket 133, secured upon the top plateof the machine and adapted to be shifted longitudinally thereon for apurpose which will' presently appear. Said bar is provided with a pairof ears 134 at a suitable point, and between them is pivotally mountedthe dog 135. Said dog is'rounded at its front end, as shown at 136 atone corner, and diagonally opposite said corner it is rounded at itsrear end, as shown at 137. It is pivotally mounted near its middle upona pin 138, carried by the ears 134, and is bifurcated, and spirallyencircling said pin and secured thereto at one end is a spring 139,which bears at its opposite end with a yielding pressure against the dogforward of its pivot, so as to hold its rear end pressed yieldinglyagainst the bar 132, which limits its operation in the directionopposite to that indicated by the arrow, Fig. 14. When the bar 132 is inits normal or retracted position-that is, when the spring 141, whichencircles it and bears at its opposite ends against the frame 42, andthe head or enlargement at the rear end of said bar is expanded-said dogis just rearward of the cam- Wheel 41, so that when the bar is moved orslidin the direction indicated by the arrow,

Fig. 5, it engages one of the spiral flanges or ribs of said wheel andcauses the cylinder to rotate a certain distance, the distance beingdetermined by the length of movement of said bar. For instance, when itis desired to space only a single line the stop-bracket 1'33 occupies apoint upon the top plate, which bears such relation to the stop-pin 131that the spring 1&1 will be compressed only sufficient to force the dogto engage one spiral flange or rib of the cam wheel for half its length,and consequently turn the cylinder only the distance mentioned. \Vhen itis desired to leave a double space bet-ween the lines, said bracket 133is shifted upon the top plate to a point nearer said stop-pin 131, sothat when the carriage returns and the head of said sliding bar strikesthe bracket the spring ltl will be compressed as before, and the barslid forward a distance equal to or slightly exceeding the width of thecamwheel 4:1, and consequently by engaging one of its spiral flanges orribs for its full length will turn the carriage and therefore feed thepaper sufficiently for double-spaced writing, as will be readilyunderstood. As the new line is printed and the carriage advances, thepressure on the spring is ultimately removed to permit it to return thedog to its original position at the inner side of the cam-wheel, that itmay rotate the cylinder another step when the carriage recedes under theaction of its returning spring. This backward-sliding movement of thebar 132 is more particularly described hereinafter.

In order that the walking-beam may be returned to its original positionafter each depression, we employ the retractile spring 142, secured atits opposite ends to said beam and to a pin projecting from the backwall of the framework, as shown clearly in Fig. 2; but it is to beunderstood that the spring 17, which connects the frame 16 and the arm13 of the shaft 14, is of such strength that when said swinging frame isoperated it instantaneously imparts a corresponding movement to therock-shat t and the walking-beam, overcoming the resistance of thespring 142 and the springs 112 and 117, as the case may be, forreturning the carriage to its original position, and at the same timeadjusts the ribbon. Immediately the arm 13, however, strikes the pin 18the movement of said shaft and said walking beam is arrested, while thatof the swinging frame continues, owing to the stretching of the spring17. This arrangement is provided in order to insure that the carriageand the ribbon have come to a full stop before the key strikes thelatter and makes the required impression upon the paper, therebyinsuring against blurred work. In practice, by the time the type leverhas completed threefourths of its upward stroke the carriage and ribbonhave come to a full stop and are prepared to receive the stroke of saidtype-lever.

In order to limit the rotatable movement of thereto .or to the frame,atits ends.

the cylinder to the exact distance required, we provide a frictionmechanism which engages the cam-wheel and which is constructed asfollows: 149 designates a pin suitably supported at the front side ofthe frame 42, and 143 a curved arm which terminates in a shoe 144 at itsfree and upper end, adapted to engage successively the grooves formedbetween each pair of the spiral flanges or ribs of the cam-wheel. Inorder to hold this brake-shoe with a yielding pressure in such position,we employ a spring 145, which bears at its middle against said arm aboveits pivot and has its ends coiled around the pin 149 and secured Toassist said spring in holding said brake-shoe in place, thoughprincipally to prevent any lat eral or twisting movement of thebrake-shoe, the spring-arm 146 is connected at its opposite ends to thearm 1&3 and to the adjacent arm 36 of the carriage.

' In case it is necessary or-desirable after a line has been printed toreturn the carriage for only half its distance or any distance short ofthe full distance the curved outer or front end of the bar 182 isgrasped and at the same time the return-key 118 is depressed. Thedepression of said key causes the operation of the dog 128 and throws itand also the pawl 11 out of engagement with the ratchet-section of thewheel 5. Immediately this takes place the spring 112 or 117, as the casemay be, rotates said wheel backward, and overcoming the pressure of thespring 141 causes the dog 135 to rot-ate the cylinder and feed the paperto space for a new line. The grip upon the said bar 132 retards thereturn movement of the carriage, so that it can be stopped just at therequired point, the return-key of course being released, so as to permitthe spring 147 to cause the reengagementof the dog 128 with theratchet-wheel, the gravity or spring-actuated dog 11 automaticallyreengaging said wheel-also, as will be readily understood, and holdingthe carriage at such point. The bar 132 then being released, the spring141 slides it back to its original position, the dog 135 of courseyielding pivotally as it engages the cam-wheel on its back motion toaccommodate or permit this return movement. The rounded shoulder 137makes this pivotal movement possible, and the shoulder 136 facilitatessuch movement when the dog is arranged as shown. It will be understood,of course, that the wheel 43 may be grasped in order to retard thereturn movement of the carriage, so that it can be stopped at anyintermediate point; but it is equally obvious that it will require anadditional movement ofthe hand in order to rotate said wheel and therebyspace for a new line. This operation of course would require a littlemore time than is occupied by grasping the bar 132.

One particular feature of this machine which possesses great advantagesover those in general use is the platen or printing-surface carriedrigidly by the carriage and en- IIO tirely independent of the cylinderor feedroller for the paper. By employing a platen or printingsurface ofthis character it is obvious than an absolutely square face or surfaceis always presented for the impact of the type, and consequently thelatter will'make at all times, provided they are kept clean, a perfectimpression upon the paper, because the platen provides a resistance forthe entire surface of the type, and consequently the impression made isclear and perfectly defined.

With machines employing a cylindrical feed-roller also, as the platen orprinting-surface, it is obvious that when the bearings of thetype-levers become slightly worn they do not always strike squarelyagainst the paper, owing to the fact that the printing-surface isslightly rounded. \Vith the fiat platen or printing-surface we employ itdoes not affect the quality of the work, whether the type-lever bearingsare absolutely perfect or not, as the type when arrested by said surfacewill be caused to impinge squarely thereagainst. This action, however,is made more positive and reliable by the use of guide-rollers 108. Thisflat platen also is an improvement over the calligraph-cylinder, as theflat surfaces of the latter, after the bearings of the cylinder andother parts of the machine have become somewhat worn, are not alwayspresented squarely to receive the type-impressioln, and consequentlyragged work is the resu t.

Another feature to be noted is the springclips 104, which embrace thetype-levers, as shown most clearly in Fig. 6. Said clips at their freeends provide a continuous but yielding pressure at opposite sides of thetype-levers, and as the clips themselves are fixed rigidly to the topplate of the machine it is ob vious that the wearing of the bearings orpivots of said type-levers does not affect their alinem cut. Theconnection between the pull or link rods 98 and said type-levers is ofthe same character.

A recapitulation of the entire operation is not believed to benecessary, and it is to be understood, of course, that various changesin the form, proportion, and detail construction of the parts will bemade and that mechanical equivalents may be substituted for thedifferent parts without departing-from the spirit and scope orsacrificing any of the advantages of our invention.
